Why does my code only store the last line of the text file in the array, instead of all lines?

Reading Text File Lines into Array Elements

Question:

In this code snippet for reading a text file line by line into an array:

<code class="php">$file = fopen("members.txt", "r");
while (!feof($file)) {
  $line_of_text = fgets($file);
  $members = explode('\n', $line_of_text);
}
fclose($file);</code>

Why does the $members array contain only the last line of the text file, rather than an element for each line?

Answer:

The provided code correctly reads lines from the text file but encounters an issue in creating the array of lines. Using explode('n', $line_of_text) within the loop overwrites the $members array in each iteration, ultimately storing only the last line.

To resolve this issue, use file function instead:

<code class="php">$lines = file($filename, FILE_IGNORE_NEW_LINES);</code>

This function directly creates an array where each element represents a line from the text file. Using FILE_IGNORE_NEW_LINES skips the newline character from each line, ensuring the array contains only the line content.
